EIN for a California LLC in 2026

Last updated: 2026-10-07

An Employer Identification Number (EIN) is your California LLC's federal tax identity — needed for a business bank account, hiring employees, and filing taxes. The EIN itself is free from the IRS. This guide covers the IRS application basics, the responsible-party and SSN/ITIN rules (including for non-residents), and the California-specific tax registrations that come with an EIN. llcformation.io/ is an independent private service — not a government agency — and this is general information, not tax advice.

What an EIN is and why your California LLC needs one

An EIN (Employer Identification Number, also called a Federal Tax ID) is a nine-digit number the IRS assigns to your LLC — your business's federal tax identity.

You will need an EIN to:

• Open a US business bank account — most banks require one.
• Hire employees — no payroll or employment tax filings without it.
• File federal taxes for the LLC.
• Work with payment processors and vendors that request a tax ID.

Even a single-member California LLC with no employees usually gets one, because banks ask for it. The IRS issues EINs for free — there is no legitimate IRS fee, ever.

How to apply: the EIN itself is free

The IRS offers three routes:

1. Online application — fastest for eligible applicants (the responsible party needs an SSN or ITIN). The EIN is issued at the end of the session.
2. Fax (Form SS-4) — the completed form goes to the IRS; the number is returned by fax.
3. Mail (Form SS-4) — slowest; used when the applicant has no SSN/ITIN.

Rules to remember:

• Apply only once — an LLC gets exactly one EIN.
• Apply after formation, using the LLC's legal name and California as the formation state.
• Use irs.gov only. Third-party "EIN filing" sites charging a fee are not the IRS.

We handle the application through our EIN assistance service — you answer a few questions, we handle the IRS paperwork. Pricing to be confirmed — contact us on WhatsApp at +92 314 9150035 for a quote.

Responsible party, SSN/ITIN, and non-resident realities

Every application names a responsible party — the individual who ultimately owns or controls the LLC:

• The responsible party must be an individual, not a company.
• The online application requires the responsible party to have a valid SSN or ITIN.
• Applicants without an SSN or ITIN — including non-resident founders — apply by fax or mail with Form SS-4 instead.

For non-US residents: you can form a California LLC and obtain an EIN without an SSN or ITIN. The SS-4-by-fax route is the standard path, and authorized designees can act on the application. Expect this to take meaningfully longer than an online issuance — plan your bank-account timeline accordingly. You do not need an ITIN first just to get the EIN; the SS-4 route exists for exactly this case.

One California-specific note for non-residents: forming here means the $800 annual franchise tax applies regardless of where you live, so factor that into your state choice before you file.

California tax registrations: what the EIN does not cover

Your EIN opens the federal door — California then has its own, substantial set of obligations:

• Franchise Tax Board (FTB). Every California LLC owes the $800 annual franchise tax, even with zero income. The first-year exemption for LLCs formed in 2021–2024 no longer applies to new formations. Registration/payment with the FTB is separate from your IRS EIN.
• Pass-through income tax. LLC members pay California's graduated individual income tax (1%–12.3%, plus a 1% surcharge on income over $1M) on their share of profits.
• Hiring in California. Once you have employees, you register with the Employment Development Department (EDD) for payroll taxes, unemployment insurance, and state disability insurance — using your EIN as the employer identifier.
• Seller's permit. If you sell taxable goods, you register with the California Department of Tax and Fee Administration (CDTFA).

The EIN does not register you with any of these agencies automatically. When we assist with your formation, we flag which California registrations fit your business so nothing is missed.

EIN timeline and next steps

General timeline guidance (the IRS does not commit to exact dates):

• Online (SSN/ITIN holder): fastest — typically issued in the same session.
• Fax (Form SS-4): manual IRS review; allow weeks.
• Mail (Form SS-4): slowest.

Sensible order: form the LLC (California Articles of Organization, $70) → apply for the EIN → open the bank account → register with the FTB and any other California agencies you need.
